A couple of 17mm ring spanners or, better, a socket and spanner will get you in. And always nice to leave the place as found, too.

Good work with the SRT Col - Brewery Shaft next Thursday methinks! :lol:

Thanks for the update.
My guess is nuts were used to upgrade the defunct bolt put in the guy who rebuilt the entrance, Robert Bunting, sometime around 17 years ago!
On one occasion late last year,we found the entrance door open and clearly anyone could enter.
I secured it, using bolts, since, I felt kids could enter and may have an accident
Since I did not use any super glue on the the threads, I assume the land owner also did not like the idea of the door being open and remodified our work.

There is an original bolt welded to a chain - maybe 1/2 UNF but the threads are so worn its hard to tell. Each time I've been in, over the years, the door has been secured by an M10 bolt & nut. Ideal really, keeps the numpties out. Hats off to the builders, mind, there's some serious steel in there :thumbup:

As you say the original bolt was so worn as to useless.
When I refitted the bolts and angled pieces, the bolts you mentioned had disappeared and so the steel door was not locked.
I felt it could not be left like this, hence my work,on the bolts.
Our friend Robert is an excellent fitter, when at Derby Tech, clearly his tutors also agreed with my assessment, and rewarded his efforts by awarding him the Rolls Royce medal for the best practical fitter.
